These are the very high end vehicles, as seen on the motoring shows with a mention of how you can't buy one because they are all sold. They are sold to the existing customer base, selected customers only. In some way this is like BitCoin in that every one of these vehicles will have some log book back to when it was 'mined from some factory in Northern Italy'. Unlike BitCoin these cars are real things with engineering wonder to them.
We also get told that these 'halo cars' cost the manufacturer 'twice' what they retail at. So the Bugatti creations of the VW group 'apparently' cost far more to research and develop than was recouped over the car sales. The project as a whole being like A380 financing - the R+D never paid off. This 'legend' goes back to the first supercars for the road - the Porsche 959. Even the rebooted Ford F40 was with this same legend.
What is going on here is a genuine collectors market with vehicles actually getting raced, repaired, rebuilt and polished. This is an expensive hobby.
Beneath this market something else is going on and I am sure finance has a lot to do with it. High end SUVs are desirable for people who like such things but they must depreciate faster than I get paid and they don't seem to have the mechanicals to last more than 5-10 years on the roads. Where do all the old Land Rover group luxury products go? Maybe there is some part of Serbia or somewhere that takes all these vehicles and they serve out a long and dutiful life, but I suspect not. The only way I can see these products as viable is if the manufacturer offers the finance to make it so.
